My father and I have been working on wooden foot drives, based on a metal design we saw on Jerry Greene's R2-R9 blog. The motors are 24-volt E-100 scooter motors. The wheels are scooter wheels. The belts are from Polybelt, purchased on eBay.
The wheels spin and the ankle cradle seems to work, but we're going to rebuild the foot drive and ankle holder as one part.
